A student wants to determine the melting point of water as part of an investigation into the strength of electrostatic forces. The student considers determining the freezing point of water instead. Is this a valid option?

a. No, it is not because the freezing point is not related to the melting point.
b. Yes, it is; but determining the freezing point is likely to be more difficult.
c. No, it is not because the freezing point is not related to electrostatic forces.
d. Yes, it is; and determining the freezing point is likely to be more accurate.
